A documentary about its titular talent manager, Supermensch: The Legend of Shep Gordon, directed by writer-actor Mike Myers, has the potential to be a slice of yawning, self-congratulatory star-fuckery of the highest order. After all, in addition to its famous director, it has plenty of recognizable celebrities who all line up to sing the praises of its subject. And yet, thanks to whip-smart pacing, this warm-hearted and unfussy nonfiction valentine emerges as an engaging portrait of a life less ordinary — a man who embraced and promulgated selflessness, even while, in his early days, indulging in druggy partying and frequently sporting a T-shirt that read, “No head, no backstage pass.” For the full, original review, from Paste, click here. (Radius/TWC, R, 84 minutes)
